Ahh....the cocktail onion. Flavor and glamor collide. It’s been said that once you “Go Gibson,” you never go back. No longer the stepsister to 007’s martini. Mad Men and bons vivants everywhere are rediscovering the Gibson cocktail thanks to Mario Onions. Pickled, bold and crunchy! Cocktail Onions bring panache to the classic gin and vermouth cocktail.
